    Remove loaders with removeChild

    Hello, I have a parent swf that loads in 6 little swfs. However, I have a button which should remove the loaders from the stage, no matter which one it is from the 6. At the moment I can only remove one of them because of the way(a stupid way) I have coded the application. So, when i click on the button which is supposed to remove whatever loader is currently sitting on top of my parent movie, it only removes one of the loaders - the one which is named first under my resetAssets function.

    I can not have:

    removeChild(ldr);
    removeChild(ldr2);
    removeChild(ldr3);
    etc.

    because only one of them is being displayed at the time and flash goes like "hey dude! where are the others you want me to remove then!?"

    I suppose the whole code has been built up poorly and I should loop the swfs through one loader instead of having a loader for each swf.. Then I could just remove the loader no matter what sits in there..?

    Well, I'm not good in coding and would appreciate help from anyone really as it is not a rare or difficult issue.


    Code:
    //imports
import flash.filters.*;
import flash.events.*;
import flash.display.Loader;
import flash.display.Sprite;	



var ldr:Loader = new Loader();
var req:URLRequest = new URLRequest("load_XML.swf");

var ldr2:Loader = new Loader();
var req2:URLRequest = new URLRequest("load_XML2.swf");

var ldr3:Loader = new Loader();
var req3:URLRequest = new URLRequest("load_XML3.swf");

var ldr4:Loader = new Loader();
var req4:URLRequest = new URLRequest("load_XML4.swf");

var ldr5:Loader = new Loader();
var req5:URLRequest = new URLRequest("load_XML5.swf");

var ldr6:Loader = new Loader();
var req6:URLRequest = new URLRequest("load_XML6.swf");

	switch(evt.target.name) {
